The many health hazards associated with consumption of poultry produced in the United States may be divided into two categories: (1) health hazards associated with consumption of any chicken flesh, and (2) health hazards associated with the methods of animal agriculture practiced in the United States.
A star topology is a LAN architecture in which the endpoints on a network are connected to a common central hub, or switch, by dedicated links. Logical bus and ring topologies are often implemented physically in a star topology, which is illustrated in the following figure.
Tree Topology integrates the characteristics of Star and Bus Topology. Earlier we saw how in Physical Star network Topology, computers (nodes) are connected by each other through central hub. And we also saw in Bus Topology, work station devices are connected by the common cable called Bus.
